The answer is 6%
47,700-45,000=2700
2700/45000=0.06
0.06x100= 6%
Answer:
(3x+1)^2
Step-by-step explanation:
Answer: [D]: 98°<span> .
______________________________________
Explanation:
______________________________________
Since vertical angles are congruent;
and since </span><span>∠A and ∠B are vertical angles;
then: m</span>∡A = m∡B .
______________________________________
So given: m∡A = 98° ; then m∡B = 98° .

The surface area of the table tennis ball will be around 1256.64 mm².
<h3>What is the sphere?</h3>
A sphere is a 3D geometrical object which has a radius and becomes a point that revolves around a fixed point called the center.
A sphere has surface area and volume based upon the radius of the sphere.
For example, if you have a sphere of radius r then its surface area will be 4πr² and volume will be (4/3)πr³.
The table tennis ball is the form of a sphere.
Given that,
The diameter of a table tennis ball is 20
Radius(r) = 20/2 = 10 mm
Surface area of an sphere = 4πr²
So,
Area = 4π(10)² = 1256.64 mm².
Hence "The surface area of the table tennis ball will be around 1256.64 mm²".
